Edgar Rice Burroughs 
Tarzan and the Madman [EPUB ebook] 

Here is the most exciting and dangerous adventure of them all, in which Tarzan of the Apes is faced with some of his most baffling challenges ever! A beautiful white girl on safari is captured by a lost civilisation of semi-pagan tribesmen in inaccessible jungle, and worshipped as a prisoner goddess… Two ruthless crooks from across the ocean, on a feverish hunt for a lost horde of gold in Tarzan’s territory, plunder the innocent folk and creatures of the forest in their relentless search… And a young man – strong, and bronzed and dressed in a loin-cloth – calls himself ’Tarzan’, and causes chaos and confusion among all but the most faithful of the real jungle hero followers.
